* Question
| How are the words and halfwords of the memory defined? |
* Answer
| The ARM processor directly supports data types of 8-bit bytes, 16-bit half-words, or 32-bit words.Among them, four consecutive bytes starting from an address divisible by 4 constitute one word, and the data type of the word is four consecutive bytes.The consecutive 2 bytes starting from the even address form a halfword, and the data type of the halfword is 2 consecutive bytes. |
